Ron Washington has a history of working with young players and identifying and working through issues, as long as they buy in and put in the work. I don't think there's much doubt that Schanuel is that kind of player who'd put in the work, and he really does have some quality ABs even if the results aren't there yet.
Suarez on the other hand is a bloated useless weakminded knockoff lefthanded Bartolo clone who should be DFA'd
